Criminal Investigation Notes

The physical evidence side had already collected a series of evidence at Chen Xuexian's home, and brought all the materials back to the General Administration for research.

Lu Junchi took all the photos and on-site investigation materials, and handed over those few images to the sound laboratory of the Physical Appraisal Center.

At present, voiceprint recognition has been recognized as an identification method in the world.

The human voice is related to the soft palate, tongue, lip shape, and teeth.

Those voiceprints are like fingerprints. Even if you deliberately imitate someone else's speech or lower your voice, the displayed voiceprint will still have inherent characteristics.

In the afternoon, during the lunch break, the crime team finally got the comparison results.After voiceprint identification, the man's voice in that video was Qiu Jiarong's.

Several people in the office were working overtime at noon, only Su Hui lay on the sofa.

The office at noon was full of the smell of food, but he only ate a little, and then he said he was sleepy, and after lying down for a while, he lost his voice. Lu Junchi walked over to have a look, Su Hui was sleeping soundly at this time.

He curled up his whole body, using a pillow as a pillow, and Lu Junchi put a piece of clothing on him.He seemed to have noticed something, his body moved, and he buried his face in his clothes, only revealing the long eyelashes and the mole at the end of his eyes.

Lu Junchi made a gesture of silence to the others. In order not to quarrel with him, everyone's discussion of the case turned into an online discussion.

Zheng Baifan looked at the result and frowned and typed: "Qiu Jiarong, that dull programmer? It doesn't look like a murderer at all."

Qiao Ze typed: "A murderer doesn't have the word murderer written on his face. You can see how he fights, but he is not cowardly at all."

"But this recording is not complete, there is no subsequent fighting process, and it can't prove that he is the murderer." Qu Ming turned to look at Lu Junchi, "Shall we call him again?"

Lu Junchi pressed a line: "Let's call here and ask."

Just when the discussion reached here, the phone on the desk rang suddenly. In the quiet office, the ringing of the phone was a bit abrupt.

Afraid of waking Su Hui up, Xia Mingxi hurried over to pick it up as soon as it rang. After hearing a few words, he raised his head and whispered to Lu Junchi, "Captain Lu, a middle-aged woman came from the alarm station and said There is a case report. She said that she is Qiu Jiarong's mother."

After hearing this, Qiao Ze jumped up from the chair, but pressed his hands on the keyboard to type: "I didn't expect that, does she have any clues?"

Qu Ming typed: "I can't tell, is this mother trying to kill relatives righteously?"

It seemed that they had to listen to what the mother had to say before calling Qiu Jiarong over.

Lu Junchi closed the file in his hand and typed: "Qiao Ze, go and lead her to the interrogation room, I'll be there right away."

Qiao Ze got up immediately after taking the order, and made an OK gesture to Lu Junchi.

Lu Junchi walked to the sofa and called Su Hui softly: "Mr. Su, wake up."

Su Hui had been woken up by the ringing of the phone just now, and now he opened his eyes and squinted them like a cat.

Lu Junchi had the illusion that he didn't raise two cats at all, but three cats.And the one in front of me is the most beautiful, the most precious, and the hardest to serve.

Su retracted his body, and after a while he rubbed his eyes and let go of the pillow on his head: "What was that phone call just now? Has the case progressed?"

Lu Junchi reported to him obediently: "Qiu Jiarong's mother is here, let's go over and ask."

Su Huan gave a hum, and then stood up for a while, Lu Junchi poured him a cup of hot water, and went to the interrogation room by himself.

When Su went back, Lu Junchi had already brought Qiao Ze in to inquire.

Qu Ming called out: "Teacher Su."

Su Hui nodded and sat beside Qu Ming.

In the interrogation room, Lu Junchi looked at the 50-year-old middle-aged woman in front of him. Her face was yellowish, her eyelids were swollen, and her hair was permed and curly, slightly messy.The woman has heavy dark circles, probably because she hasn't slept well recently.

When she came to the police station for the first time, facing the two policemen, her hands trembled a little, and her expression was not natural. She kept holding a bag in her arms tightly, looking very nervous.

Lu Junchi looked at the registration form. This woman is called Qin Yiyun. She is 56 years old and lives in Huadu. She is currently retired.

After checking the information, Qiao Ze asked her, "Auntie, can you tell us why you came to the headquarters today?"

Qin Yiyun sobbed, tears flowed from the corners of her eyes again, she covered her face with her hands: "I mustered up a lot of courage to come here... I... I really didn't expect that my own son, It will be because of a woman that I have come to where I am today..."

Qiao Ze comforted: "Auntie, don't worry, speak slowly."

Qin Yiyun wiped the corners of his eyes, and then began to say: "I suspect that my son killed someone..."

Then she explained: "It's like this. My son Qiu Jiarong... has always been shy. He didn't find a partner when he grew up. After the age of 25, our old couple started to worry. We will arrange various blind dates for him. This year, several A month ago, my son suddenly told me that he was in love."

Qin Yiyun spoke a little messily, and she wiped her tears again and continued: "I was very happy at first, and our old couple were also very supportive, and I was thinking about when he would be able to bring the girl back to see. But I didn't expect, This was the beginning of a nightmare. Since then, he has become a little strange... He usually keeps his mouth shut, and always tells us about that girl, that she cooks delicious food, and that she is a virtuous person. When we started, It’s normal to feel that the child is in love.”

"But the more time passed, the more I felt that he seemed to be possessed by a demon. He didn't pay attention to work anymore. He often didn't eat at home, and when he came back, he just looked at his phone. If the other party sent him a message, he would be as happy as a child. Yes, once the other party ignored him, he began to fidget. Until one day, he came back with a bruised nose and a swollen face, all wounds on his body... said he had a fight with someone outside..."

This is probably the time when Qiu Jiarong and Shao Changqing fought on the surveillance camera.

"I didn't know what it was at the beginning. It wasn't until a while later that he admitted to me that it was because of that woman that he fought with others. After that, he was even more distraught and often didn't go home."

Then Qin Yiyun continued: "I advised him at that time that there are many women in the world. If the one doesn't fit, then change another one, but he said he wanted that woman. Once after drinking some wine, he cried and said to me , 'Mom, if she doesn't want me, I don't want to live anymore.' After hearing this, I was terrified, and quickly enlightened him."

Lu Junchi frowned when he heard this, he remembered what Chen Xuexian said before.He felt that this man had already been firmly controlled by Chen Xuexian, maybe he had also been PUAed, unknowingly, controlled by that woman.

"Later..." Qin Yiyun gritted his teeth before saying this, "I have two apartments in my house. I live in one, and the other is a wedding room for my son. He lives alone. I go to clean his house every once in a while, just recently, I went to him to clean the room once, and then found some blood stains on his clothes and shoes...they were very small blood stains, maybe he didn’t I found out... I... I was very panicked when I saw it."

Speaking of this, she clenched the cloth bag in her arms even more tightly: "I hesitated for a long time, should I discuss it with my wife. In the end, I came by myself..."

Lu Junchi and Qiao Ze were shocked when they heard this: "Auntie, did you bring the clothes?"

"I brought it here." Qin Yiyun took out a men's plaid shirt from the side bag while speaking, and handed it to Lu Junchi.

Lu Junchi checked it, and there were indeed some imperceptible blood stains on the wrist of the clothes. He thanked: "Thank you, Auntie, we will conduct a laboratory test for comparison."

If the blood on the clothes belonged to Guo Chengfeng, then it would be an important evidence.

It is not easy for the mother in front of me to report and expose her own blood relatives.

Qin Yiyun covered his face and began to cry again when he said this: "I... I had been mentally prepared for a long time before I came here. I thought about whether I should wash off the blood stains on this clothes, and I also thought about whether I should wash it off or not. Keep it a secret... But... But I can't... I don't want to see him getting deeper and deeper. He... He has become more strange recently. I heard that he took a long vacation with the company and often Not going to work, and he sometimes goes out, but there is a fruit knife missing from the knife holder at home. I am really afraid, I am afraid of what will happen again, I am afraid of what he will do, and it will be irreparable. Blunder……"

Qiao Zejia asked: "Auntie, Qiu Jiarong didn't know you came here today?"

Qin Yiyun nodded: "He probably didn't know. I came here without telling him..."

Lu Junchi said: "Auntie, what you did is right. We will pay attention to the clues you mentioned. Monitor his behavior."

Hearing this, Su Hui in the outer observation room frowned slightly.

Qiu Jiarong is still preparing to kill, will this killing continue?

Who will be his target?

The light rain last night swept away the gloom in the city, and when it was time to get off work, the office was a little quiet.

This is a high-end office building located in the center of Huadu. In the investment company on the second floor of No.20, Shao Changqing sat in his office. identity of.

It was past nine o'clock in the evening, and Shao Changqing took out the dinner he had brought.

It was a dumpling stuffed with meat. The dumplings were beautifully wrapped. The skin was thin and the filling was large, exuding a tempting aroma.

Shao Changqing took his time and went to the company's tea room to heat up the dumplings in the microwave.

He brought vinegar himself, took out a plastic dish, poured the vinegar bag into it, picked up a dumpling and took a bite.

The smell of meat overflowed in his mouth, he chewed it with satisfaction, and couldn't help squinting his eyes.

The HR department is next door, and the HR director is also working overtime. At this point, everyone is hungry. He came over and said, "Hey Mr. Shao, what are you eating?"

Shao Changqing said: "Dumplings."

The personnel director said: "It smells so good."

Shao Changqing proudly said, "Naturally, my wife made it."

The personnel director smiled: "How long have you been in a relationship? Before I sent out the red envelope, my wife called me first." He swallowed and asked, "What meat stuffing?"

"Pork with mushrooms."

The umami of the gravy and the special aroma of the mushrooms are especially delicious.

Generally speaking, the other party will take the initiative to taste it, but Shao Changqing didn't mean that at all, the personnel director hadn't had time to eat breakfast, and the smell couldn't bear it, so he pulled his face and said, "Can you give me a taste? "

After hearing this, Shao Changqing shook his head, stretched out his hand to cover the dumpling lid, and said with a reluctant look: "You can eat anything else, the dumplings made by my wife are not good."

The personnel director said: "Stingy!" Then he returned to his office.

Shao Changqing was eating dumplings when suddenly the phone rang on the table. The landline in the office is basically just a decoration these days. He didn't expect someone to call, and it was a big night when he was working overtime.

Shao Changqing answered the phone, hummed a few times, and became more serious the more he listened: "Okay, I understand." His class didn't care about extra time, and started to pack his things.

After the things were packed, Shao Changqing looked at the dumplings in front of him, but he still couldn't bear it. He ate the dumplings whole, and then hurriedly got up and prepared to go home.

In Huadu at night, it was already past ten o'clock in the evening, and the weather had already turned cold. Today is a bit dull, and the water vapor content exceeds the standard. It seems that an autumn rain is brewing.

Shao Changqing, who had finished working overtime, took the last train out of the subway exit. He was walking on the road, passing a somewhat remote alley, suddenly there was a sound of footsteps behind him, and a figure caught up with him.

"Who!" Shao Changqing turned his head vigilantly. The person behind him was about 1.7 meters eight, wearing a black hood and wearing a mask to cover his face tightly.

The man pulled down his mask, revealing a man's face, it was Qiu Jiarong.

Now, that man's face is pale, completely gone from the elegance and dullness of the past, replaced by a cold cruelty.

Shao Changqing looked at him, full of vigilance and vigilance: "You are the one who fought with me last time... the one named Qiu, what do you want to do?"

"I want to ask about her." Qiu Jiarong looked around, the surroundings were pitch black, his face became ferocious, "I know, you must have hidden her! Give her back to me! "

This place is very quiet, only the occasional calls of wild cats on the side of the road can be heard.The air was about to freeze.

Shao Changqing shook his head: "I don't know where she is, she hasn't contacted me for a long time. You were with her in the end!"

Qiu Jiarong froze for a moment: "Nonsense! You are talking nonsense! It is clear that you took her away!"

"The police are looking for her too." Shao Changqing touched his nose and said, "I guess it was because you did some bad things that caused her to escape?" His expression showed a trace of sarcasm, "You Didn't you keep saying that woman loves you more? Why do you ask me where she is? If you came to me today, it was just to ask about this, but I don't know at all. "

"I don't believe your nonsense! Where did you get her?" Qiu Jiarong's face became hysterical, and he drew a knife from another pocket.

Shao Changqing looked at him and raised the corner of his mouth: "Crazy, she doesn't want to be with a lunatic like you either."

This sentence hurt Qiu Jiarong, holding a knife in his hand, he stabbed towards Shao Changqing.

Shao Changqing didn't get scared until this time, so he dodged in fright and called out: "Help!"

He wanted to escape, but his legs and feet were weak, and he ran a few steps forward before falling to the ground.

The knife in Qiu Jiarong's hand slashed straight at Shao Changqing.

As soon as Shao Changqing fell, the knife cut through the air, making a whoosh sound of breaking through the air.
